About Zachary Seow, LMSW

Zachary Seow is an associate therapist at Brightline’s Columbus Circle clinic, providing care under the supervision of Brittany Armstrong, LCSW.. He has experience working in both hospital and school settings, practicing evidence-based approaches such as cognitive behavioral therapy (CBT), dialectical behavior therapy (DBT), and motivational interviewing. 

Zachary has worked with kids and teens who are experiencing anxiety, depression, and ADHD, as well as those on the autism spectrum. While he has primarily engaged in individual therapy, Zachary has also worked with groups of students in school settings to cultivate social-emotional learning.

What excites Zachary about working in mental health is witnessing growth — both in the families he works with and within himself. Personally, Zachary is passionate about fitness and his faith, and he finds inspiration when he sees a stumbling block become a stepping stone towards progress.

“I am passionate about helping children and families thrive in life and mental wellness. Because kids don't always have the words for their struggles, I am dedicated to making them feel seen and heard. Let's normalize big emotions, listen without judgment, and ensure no child faces their mental health journey alone."

Christina Sampson, MSW, LCSW

Therapist star
“Behaviors labeled as 'bad' or 'challenging' are usually a child's body doing its best to stay safe based on past experiences. As a therapist, I'm passionate about using trauma-informed guidance to help children and their families move out of survival mode and build healthier, more resilient lives.”

What is an associate therapist?

Associate therapists have earned their master’s degree in social work, psychology, marriage and family therapy, or counseling. They have a limited license to practice under supervision, and are completing their supervised hours at Brightline to work toward their independent licensure. That means that all of the work they do with your family will be supervised by one of Brightline’s licensed providers. Their supervising provider will review all session notes, care plans, conversations, and recommendations to ensure the approach to your child’s treatment is aligned with our standards of providing high-quality, safe, and ethical care. Supervising provider names can be found on each associate therapist provider page on our website; the associate therapist will also share who their supervisor is at the start of care.
